Top Forums Shell Programming and Scripting Issue in shell script Post 302964654 by Don Cragun on Sunday 17th of January 2016 05:36:35 PM

Please answer Scrutinzer's question: Is this homework?

If it isn't there are a few other questions that need to be answered:
  1. What shell are you using?
  2. Note that in your sample data, you have two items that have the same "highest quantity" sold and two other items that have the "highest number of sales transactions". How do you determine which should be given the "highest" label? (Or, more to the point, why don't you report all items with the same statistics when there is a tie?)
  3. You said you wanted your script to print three values. Are all of the files your script creates used for later processing? Or, are they just artifacts left over after your script completes?
  4. Could you please explain why you believe that the following code is needed in your script?:
Code:
	cut -f1 -d ',' log |grep -v item| sort -u >> 1
	for a in `cat 1`
	do
	touch $a
	done

memcached-tool

MEMCACHED-TOOL(1)					      General Commands Manual						 MEMCACHED-TOOL(1)

NAME

       memcached-tool - stats and management tool for memcached

SYNOPSIS

       memcached-tool <host[:port] | /path/to/socket> [mode]

DESCRIPTION

       memcached-tool  is  a Perl script used to print statistics from a running memcached instance.  The first parameter specifies the address of
       the daemon either by a hostname, optionally followed by the port number (the default is 11211), or a path to UNIX domain socket. The second
       parameter specifies the mode in which the tool should run.

MODES

       display
	      Print slab class statistics. This is the default mode if no mode is specified.  The printed columns are:

	      #      Number of the slab class.

	      Item_Size
		     The amount of space each chunk uses. One item uses one chunk of the appropriate size.

	      Max_age
		     Age of the oldest item in the LRU.

	      Pages  Total number of pages allocated to the slab class.

	      Count  Number of items presently stored in this class. Expired items are not automatically excluded.

	      Full?  Yes if there are no free chunks at the end of the last allocated page.

	      Evicted
		     Number of times an item had to be evicted from the LRU before it expired.

	      Evict_Time
		     Seconds since the last access for the most recent item evicted from this class.

	      OOM    Number of times the underlying slab class was unable to store a new item.

       stats  Print general-purpose statistics of the daemon. Each line contains the name of the statistic and its value.

       dump   Make a partial dump of the cache written in the add statements of the memcached protocol.
